CarlislePaWx Posted January 19, 2019 Share Posted January 19, 2019 looks like the first of the heavy snow about to hit Chambersburg and then head up I-81 way. Does look like it will turn into a rapid "thump" when it arrives. Link to comment Share on other sites More sharing options...

CTP PTC forecasts were a 2-4 inches higher in Central Dauphin and Lebanon counties vs. Cumberland + Perry but Carlisle is sitting pretty right now.

Blizzard of 93 Posted January 19, 2019 Share Posted January 19, 2019 The Euro at 12z also brought the snow line further south & east than its run last night. The 6 inch snow line runs just a few miles to the north of I-81 & I-78, & the 4 inch line runs across the turnpike through the LSV. Link to comment Share on other sites More sharing options...
MAG5035 Posted January 19, 2019 Author Share Posted January 19, 2019 This opening salvo of snowfall is pretty impressive in the Altoona-Bedford-Mount Union-Huntingdon region, heading for State College. Already a coating on all surfaces including the streets and large aggregates. Link to comment Share on other sites More sharing options...
Voyager Posted January 19, 2019 Share Posted January 19, 2019 Nothing here yet, but the temp did drop to 33, and the overcast is thicker because it got notably darker in the past half hour. Per radar it looks like it shouldn't be much longer... Link to comment Share on other sites More sharing options...

I just hope it doesn’t cause a problem on the roads with general public thinking it won’t be so bad. This will make it more fun when they bump it back up in a few hours.

WmsptWx Posted January 19, 2019 Share Posted January 19, 2019 Assuming their forecast doesn't verify, this will probably qualify as the biggest bust in a few years since the "We all blew this forecast" call from several years ago, in which PennLive called every red tagger on Earth for a statement. I wonder if CTP would be willing to perform an autopsy. I know this is the hill I will die on, but the public stance on meteorologists is bad when they're right, I feel like it would help their perception with the public if they would admit and explain a blown call a little better when they do. Not that anybody would read it. Link to comment Share on other sites More sharing options...

Dew point temps at the surface are not going to be what the issue is - it’s going to be the upper air temps by the time the main precipitation actually arrives. The 10:1 maps are printing out snow totals for the area that they just dropped the warning for that are several inches higher than how things are looking like they will play out (12z Euro Kutchera has MDT at 1” snow total for example). What was supposed to be the front end thump for LSV has ended up further away from the low and is well north than what models were showing prior to this morning. What was supposed to be the start of heavy snow around here by 2-3 pm models like HRRR runs today don’t have arriving until 7-8pm with warm air aloft right on the doorstep.

I was thinking along those lines, myself. The main slug of precipitation is still out in West Virginia, Ohio, and Kentucky. Link to comment Share on other sites More sharing options...

Yea and I think we will still get a few hours of good snow before mixing issues but at that point even 2-4” around I-81 corridor and 1-2” closer to turnpike without significant ice issues looking like they will be a factor anymore it will be below warning criteria.

Most agreed except that everyone keeps saying that DP's are not the issue but if it is not below freezing at the surface it can snow forever and is just going to melt on the roads except in the heaviest bands...that is why I keep referencing DP's. Most of the LSV has not had 5" or more on Kuchera for a day or two but we were progged to get so much sleet that the WSW might have worked out. HRRR is progging much lower qpf's all together now and that probably played into it. HRRR delayed the arrival of heavy snow to 5-7PM almost 12 hours ago so if that had dropped it this AM it would have seemingly made more sense but not a big deal either way.

CarlislePaWx Posted January 19, 2019 Share Posted January 19, 2019 Wow...while not totally shocking, it is pretty surprising to see the pendulum swing back so quickly. For my point and click they have me as 1-3" this afternoon and 1-2" this evening before a mix later this evening, and then a change to plain rain overnight. First time for plain rain alone with no other ptypes. BTW, the radar shows the darker greens over me right now and I have literally nothing falling from the sky! I thought for sure that would be heavy snow and it would start instantly since I had the snow falling earlier with light blue over me. Go figure. Temp back up to 34.5.

MAG5035 Posted January 19, 2019 Author Share Posted January 19, 2019 I can agree with the downgrade on the southern tier counties.. Franklin, Adams, York, Lancaster, maybe Cumberland. But I probably would've rode out the other LSV counties, I still think they get somewhat close to the 5" threshold (3-4" or so) plus the dual impact with the mixed precipitation. Keeping an eye on HRRR trends, I guess we'll see if it ends up being correct on running the low right through the southern half of PA to NJ. That's quite far to the NW, and it still delivered said 3-4 in around H-burg up through Voyagers neck of the woods before changing to sleet in those areas as of the 18z run.
